Try this (provided the comments are actually _in_ the function -- in
the example you gave they are not).
> foo <-
+ function(x){
+ # comments line 1
+ # comments line 2
+ # etc..
+ x <- 2
+ }
>
> grep("^#", attr(foo, "source"), value = TRUE)
[1] "# comments line 1" "# comments line 2" "# etc.."
Also be aware of the keep.source option: ?options
